A Few Q's about the MK series

I'm planning to buy one of these, but first I'll need some info:
- Can I use real steel sights on these? I have a KSC M17 with Meprolight tritium sights on them. I really want them on the 1911 Mk III. Is this possible?
- Can I use real steel grips on these? I'd love some rosewood grips on that 1911 Mk III. Is this possible?
- Which chrome 3rd party items could I install? I'd love to install a chrome barrel, guide-rod and controls. Are they available?

1. No, the rear sight serves as an anchor for the breech assembly
2. Yes, the frame is patterned after a commercial frame
3. Unavailable to this point, the gun is still new and aftermarket companies have yet to pick up production
